Australia Post on Shopify via MyPost Business — every platform is BYO

TL;DR

Australia Post does not allow platforms to resell MyPost rates. So every AU 4PL and shipping app is bring-your-own for AusPost — merchants connect their own MyPost Business account for booking, labels, and tracking. Pack is no exception.

What Pack does add: compare your MyPost AusPost rates next to Pack Network (Couriers Please + Aramex), Pack Freight (TNT + TFM soon), and Pack Priority (Aramex Priority) negotiated rates in one Shopify checkout and label flow. Pack is not an Australia Post replacement, and BYO MyPost is not a Pack-unique feature. Free Forever includes the full product up to 100 bookings per Shopify billing cycle; Starter is $49/mo when you need volume.

Intro

Australian Shopify stores and Australia Post go together for a reason: national coverage, parcel lockers, and a rate card many merchants already negotiated through MyPost Business. The awkward bit is rarely "should I use AusPost?" — it's "how do I use my MyPost Business account inside Shopify without locking the whole store into a single-carrier trap?"

Here's the industry fact that clears up a lot of marketing fog: AusPost does not let shipping platforms resell MyPost rates. ReadyToShip, Shippit, Starshipit, Pack — any of them — you'll bring your own MyPost Business account if you want AusPost booking, labels, and tracking. That isn't a Pack exclusive. It's how AusPost works with every platform.

Pack to the Future is a Gold Coast–built Shopify shipping app for Australian merchants. Connect MyPost Business for Australia Post (industry standard), print labels, and quote those rates at checkout — then, when a satchel isn't the right tool (or AusPost isn't the best live rate for that lane), layer Pack Network, Pack Freight, or Pack Priority negotiated rates without rebuilding your stack. That's the Pack differentiator.

This post is capability education, not a MyPost login walkthrough. If you need AusPost's own portal help, use Australia Post's docs. If you're comparing label apps on total cost of ownership, read ReadyToShip vs Pack for an honest per-label vs Free→$49 compare.

Who this is for

Shopify stores shipping from Australia that already have (or plan to open) a MyPost Business account
Merchants who want AusPost and Couriers Please / Aramex options without juggling five portals
Teams burned by single-carrier risk (see the multi-carrier shipping software Australia post)
Anyone evaluating Pack vs incumbents who still treat "AusPost support" as a checkbox — remember: on AusPost, every platform is BYO

Not for: merchants hunting "MyPost Business login" how-tos — Pack won't outrank ReadyToShip on portal navigation, and we shouldn't try.

Connect MyPost Business for AusPost (industry standard)

Connect your MyPost Business means: your account, your negotiated AusPost rates (as your account allows), surfaced through Pack alongside Pack's negotiated carrier pools for rate compare, labels, and checkout.

What that unlocks in practice:

One merchant workflow — quote and label without bouncing between AusPost-only and "everything else" tools.
Honest multi-carrier choice — when Pack Network (Couriers Please + Aramex) wins a lane, you can take it without abandoning MyPost for the orders where AusPost still wins.
Checkout accuracy helpers — Product AI dimension estimation and a live residential vs commercial address checker (theme blocks, AI likelihood, customer confirm fallback, forklift vs tailgate path, typically under 100ms). Behaviours only — Pack does not publish an accuracy percentage.

For the product overview, see /services/shipping-app. For connecting carriers in-product, use Pack's KB carrier guides (connect-MyPost path) — not this blog post as a login tutorial.

Live carriers truth box

Live Pack carrier rates (Australia):

Pack Network — Couriers Please + Aramex (Pack negotiated rates — differentiator)

Pack Freight — TNT + TFM soon (Pack negotiated rates — differentiator)

Pack Priority — Aramex Priority only (Pack negotiated rates — differentiator)

Australia Post — connect your MyPost Business account (industry-standard BYO on every AU 4PL/shipping platform; AusPost does not allow reselling MyPost rates — not Pack-unique)

Do not claim "20+ carriers." Do not pitch BYO MyPost as Pack-only. Sendle, FedEx, DHL, and StarTrack are not live Pack rates.

Pack's edge: Pack Network / Freight / Priority

Keep MyPost Business connected for AusPost. The Pack differentiator is the negotiated pools:

Pack Network (Couriers Please + Aramex) — add when:

You're seeing better live rates on metro parcel lanes that Couriers Please or Aramex cover well for your SKUs
You want a managed second path so one carrier outage doesn't freeze your store (the resilience case in the multi-carrier post)
Customers need delivery choice at checkout beyond a single AusPost product

Pack Network = Couriers Please + Aramex only. It is not "every AU courier."

Pack Freight (TNT + TFM soon) — when weight/dimensions push you out of parcel networks into freight. Pair with Pack's cubic / bulky guides: volumetric weight · bulky/cubic checkout accuracy. Don't ask a parcel product to pretend it's a pallet.

Pack Priority (Aramex Priority only) — when the order needs a priority Aramex product, not the standard Pack Network shop.

Still keep MyPost connected for the orders where Australia Post is the right answer. Multi-carrier is a mix, not a divorce from AusPost — and MyPost BYO is how AusPost works on every platform, not a Pack exclusive.

What Pack is not

Not an Australia Post replacement
Not "the only app that lets you BYO MyPost" / Pack-unique BYO claim
Not a MyPost Business login / portal support desk
Not "20+ carriers"
Not a claim that Pack invents or republishes Australia Post's public rate cards as Pack's own
Not a worldwide / NZ-primary shipping SaaS

If you need AusPost-only Shopify plugins, peer compares exist (AMP Australia Post Shipping vs Pack, Joovii vs Pack) — maintain those pages; this post stays on industry-standard MyPost connect + when to layer Pack Network / Freight / Priority.

Pricing ladder

Pack pricing (AU Shopify shipping app):

Free Forever — full product (including Product AI and live carriers), up to 100 bookings per Shopify billing cycle; a multi-parcel shipment counts as 1 booking.
Starter — $49/month ($580/year). Volume unlock only — not a feature wall vs Free Forever.
Enterprise — $3,990/year. High-level includes: API access, priority SLA, white-label options, NearShip and 3PL capabilities (sales-gated — contact Pack).
Platform fee — $0.75 AUD per booking (see /kb/billing/billing-payments).
Not live / discontinued — Pack Points (discontinued); Warrior is not a live plan.

Honest TCO note vs ReadyToShip

ReadyToShip owns a lot of MyPost-adjacent SERP trust — high review volume, long tenure, free install with a variable fee from about 5¢ per label (see the live vs page for current App Store cites). Pack's model is different: Free Forever (100 bookings) → Starter $49/mo, plus $0.75 platform fee per booking.

That's apples-to-oranges. At some volumes RTS per-label wins on software cost; at others Pack's flat Starter + AI/resi tooling + Pack Network negotiated rates is the better fit. We won't invent a "Pack is cheaper" headline, and we won't claim Pack is the only place you can BYO MyPost — RTS and every peer is BYO for AusPost too. Read the side-by-side: ReadyToShip vs Pack to the Future.

FAQ

Does Pack work with Australia Post / MyPost Business?

Yes. Australia Post does not allow platforms to resell MyPost rates, so every AU 4PL and shipping app is bring-your-own for AusPost — merchants connect their own MyPost Business account for booking, labels, and tracking. Pack is no exception: connect MyPost Business for AusPost (industry standard), then compare those rates next to Pack's differentiator — Pack Network, Pack Freight, and Pack Priority negotiated rates (Couriers Please, Aramex, TNT, TFM soon). Pack does not replace Australia Post and does not claim BYO MyPost as a Pack-only advantage.

Which carriers does Pack support?

Live Pack negotiated rates today are Pack Network (Couriers Please + Aramex), Pack Freight (TNT + TFM soon), and Pack Priority (Aramex Priority only). For Australia Post, connect your own MyPost Business account — that BYO model is industry standard on every AU shipping platform, not a Pack-unique feature. Pack does not claim "20+ carriers." Sendle, FedEx, DHL, and StarTrack are not live Pack rates.

Will Pack teach me how to log into MyPost Business?

No. This guide is about connecting MyPost Business inside Pack for AusPost rates next to Pack Network/Freight/Priority — not Australia Post portal login or password recovery. Use Australia Post's own MyPost Business help for account access. Pack's KB covers connecting your account to the app once you already have credentials.

When should I add Pack Network if I already use MyPost?

When you want Couriers Please and Aramex negotiated rates beside AusPost for lane-by-lane compare, checkout choice, or resilience if one carrier has a bad week. Keep MyPost connected — adding Pack Network is a layer, not a rip-and-replace. Remember: MyPost BYO is industry standard; Pack Network is the Pack edge.

How does Pack pricing work with MyPost connected?

Same ladder as the rest of Pack: Free Forever (full product, 100 bookings per Shopify billing cycle) → Starter $49/mo → Enterprise $3,990/yr, plus $0.75 AUD platform fee per booking. Carrier postage is separate and follows your MyPost Business account or Pack Network/Freight/Priority rates as booked. Details: /pricing.
