Items sold on AliExpress are often posted on OzBargain. These are the rules for AliExpress postings on OzBargain.

• Overseas users will not be able to post AliExpress deals.
• Must have a quantity of 10 or more available.
• Non-reps / regular users are able to post deals only if the seller has a minimum of 95% feedback based on at least 30 in feedback, or a Top Brand Store, or a Choice Store.
• In addition to the above, store reps posting for AliExpress must be a Top Brand, or a Choice Store.
• Moderator discretion applies. Deals may be removed, despite meeting the above guidelines, if there are serious concerns about the legitimacy of the store's ratings, history or the item(s) being sold.

Most overseas users are representatives of companies. By banning all overseas users, this prevents undeclared reps (and 1 post wonders) from posting AliExpress deals.

An AliExpress listing with very low quantity is not a bargain because it has very limited usefulness to OzBargain members.
