Full Shipping Policy
1. General Shipping Information
All online orders are processed and shipped from our Mackay store during normal operating hours (8:30am–5:30pm, Tuesday to Friday). Our goal is to dispatch your order within 24 hours of placement, excluding weekends and public holidays.
Parts, Clothing and Accessories are shipped via Australia Post or other parcel courier. Bicycles, Frame-sets and indoor smart-bike trainers are shipped via specialist bike courier services to ensure they arrive in suitable condition.
2. Warehouse-Supplied Items
Some items on our website are supplied directly from brand warehouses interstate. Where this applies, the product page shows a note such as "Available to Order from [Brand] Warehouse — ships to Mackay Cycles, then ready for Click & Collect or local delivery in approx. 5–10 working days depending on brand."
These items route through our Mackay store before dispatch, so we can check, pack and freight them properly. Please allow the stated working days for the item to arrive with us before it's dispatched to you.
A small number of items ship direct from the supplier to your address — where that applies, the product page will say so.
