Track Winit (`WT...` / `ID...`) warehouse and cross-border parcels to Australia Post eParcel (`33...`) delivery

Winit operates both major bonded fulfillment warehouses in Western Sydney (Kemps Creek / Regents Park) and Melbourne (Truganina) for eBay/cross-border sellers as well as China-to-Australia air linehaul, inducting parcels directly into Australia Post eParcel (`33...`) and StarTrack.

Barcode transition: Winit to Australia Post

Domestic Winit parcels keep the same 92… / 420… barcode from pickup to mailbox. Pass ?carrier=winit to inspect middle-mile sort scans before USPS induction.

How the Winit → Australia Post handoff works

Follow the parcel across both networks without waiting on asynchronous webhooks or losing visibility at the handoff boundary.

1. Winit AU Warehouse Pick/Pack or China Air Linehaul (`WT...`)
Winit either picks the item from its Sydney (Kemps Creek) / Melbourne (Truganina) warehouse or flies it in from Shenzhen, pre-manifesting an Australia Post `33...` eParcel barcode.
2. Chullora / Sunshine West Facility Induction
Pallets are inducted at Australia Post's Sydney West (Chullora / Kemps Creek) or Melbourne West (Sunshine West) parcel facility (`Received by Australia Post`).
3. Australia Post `Onboard for delivery`
Australia Post delivers to your doorstep, Parcel Locker, or local Post Shop.

REST (Synchronous GET)

# 1. Query Winit middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/WT84920194833AU?carrier=winit" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query USPS final-mile scans on the same barcode:
curl "https://api.lastscanned.com/v1/track/33XHG4829104928192033" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

TypeScript (Automatic Handoff Chaining)

const headers = { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` };
const res = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}`, { headers });
let pkg = await res.json();

// If USPS is still waiting on the consolidator parcel, query Winit middle-mile hubs:
if (pkg.carrier === "usps" && pkg.status === "label_created" && /^(420\d{5})?9[2345]/.test(number)) {
  const mid = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}?carrier=winit`, { headers });
  if (mid.ok) pkg = await mid.json();
}

Winit Sydney/Melbourne Fulfillment & Cross-Border Linehaul to Australia Post Handoff FAQ

Is my Winit eBay order shipping from Sydney/Melbourne or from China?
If your Australia Post tracking shows `Received by Australia Post` in Chullora/Kemps Creek (NSW) or Sunshine West (VIC) within 24–48 hours of purchase, it shipped from Winit's local Australian warehouse; if it stays on `Shipping information approved by Australia Post` for 4–6 days, it is flying in on Winit's China-to-SYD/MEL linehaul.
How do I get the Australia Post 33... barcode from a Winit WT number?
Paste your `WT...` or `ID...` number into LastScanned to extract the linked `33...` Australia Post eParcel barcode.
