aussieBum

aussieBum is an Australian men's underwear and swimwear brand founded in 2001 by Sean Ashby, who started by making classic nylon swimwear from his dining table in Sydney after retailers turned the idea down, then sold online and later through Selfridges, Harrods and Harvey Nichols. Every garment is still designed by Sean in Sydney. The online store at aussiebum.com sells underwear lines such as WonderJock 2.0, WJ Air 2.0, CottonSoft 2.0 and Enlarge 2.0, plus swimwear, clothing and accessories, prices Singapore orders in SGD and ships here by DHL. Start from the ShopBack aussieBum page so your order earns ShopBack Cashback at the current published rate. ShopBack Singapore is an essential step before you check out at aussieBum: go through it before you pay and part of what you spend comes back as Cashback.

There is no points programme. aussieBum runs a refer-a-friend offer instead, where you and the friend you refer both get 10% off your next purchase, applied by aussieBum at checkout, plus an email list that announces sales and new releases first. A free promotional item added to an order cannot be exchanged or refunded, and gift cards cannot be redeemed for cash. You do not need any aussieBum membership to earn Cashback through ShopBack Singapore.

aussieBum drops new collections through the year and flags upcoming releases such as the AR-XPLY Cluster and Mana-Maxx collections on its homepage, with sale pricing on older lines in between. The brand notes that dispatch can slow during busy sale periods such as Christmas, so order early for gifting. For Singapore shoppers the useful windows are 11.11 and 12.12, Black Friday on 27 November 2026 and Cyber Monday on 30 November 2026, when ShopBack typically upsizes fashion rates. Sale items are excluded from the 90-day return policy, so buy sale sizes you already know fit.

The shipping page quotes Singapore directly. Economy shipping is free when you spend over S$70 and, for an order placed on 4 October 2026, showed a get-it-by window of 19 to 23 October, roughly two to three weeks. Express shipping starts from S$19.93 with a window of 14 to 16 October, roughly ten to twelve days, and the carrier listed is DHL. Orders are packed and dispatched within 1 to 2 business days outside peak sales. Multi-item orders ship together.

Uniqlo's AIRism trunks and boxer briefs are the Singapore default for humid commuting: low price, in every mall, easy to replace. aussieBum sells a narrower, more design-led range such as WonderJock 2.0 with its lift pouch, the lighter WJ Air 2.0, cotton CottonSoft 2.0 and the Enlarge 2.0 line, plus matching swimwear, all shipped from Australia. Buy Uniqlo for bulk basics you need this week and aussieBum when you want a specific cut or a swim and underwear set in one order over S$70 for free economy delivery. Both are ShopBack merchants with separate published rates.

Calvin Klein is the logo-waistband benchmark, sold in Singapore department stores and online, so you can feel the fabric and exchange locally. aussieBum is direct-to-consumer from Sydney with a 90-day change-of-mind return on non-sale items and a satisfaction guarantee, but the parcel takes roughly two to three weeks on economy delivery. Choose Calvin Klein for a quick gift from a brand everyone recognises; choose aussieBum for Australian beach-style swimwear and underwear cuts you cannot find in a mall. Compare the current published ShopBack rate on each merchant page before checkout.

aussieBum offers 90-day returns: if you are not happy, return items in original condition within 90 days from the date of receipt; sale items are not covered. The FAQ describes it as a 90-day exchange service backed by a customer satisfaction promise, so expect exchanges to be the default route and refunds where the policy allows. Free promotional items cannot be exchanged or refunded. Order changes and cancellations are accepted before dispatch through the link in your confirmation email.

aussieBum prices Singapore orders in SGD and lists Singapore as a shipping destination, with DHL as the carrier. Its terms state that DHL Express orders may be assessed for duties and taxes that aussieBum does not cover, and that by choosing DHL Express you accept any charge raised in the destination country. Low-value imported goods into Singapore attract GST under the overseas vendor rules, so check what the checkout total includes before you pay and keep the order under one parcel. ShopBack Cashback excludes taxes, duties and fees and tracks on the garments total only.

Go through ShopBack Singapore before you pay and the Cashback tracks to your ShopBack account. On your phone, open aussieBum from the ShopBack app and finish the order there. Confirm the site is showing SGD pricing for Singapore before you add your underwear or swimwear. Cashback typically tracks within 2 days and confirms in about 120 days, which covers the 90-day return window. The aussieBum page on ShopBack shows the live rate; shipping, taxes and fees are not part of the Cashback.

Yes, in line with what you keep. Cashback is based on what you keep: if you return or cancel part of an order, the Cashback adjusts to match. For a partial return or exchange, such as swapping one pair for a different size while keeping the rest, ShopBack Singapore adjusts the Cashback to what you kept. Because the merchant allows 90 days for change-of-mind returns, confirmation is set at about 120 days so the return window closes before your Cashback is finalised.
