It's against the T&Cs on two points. First, transfers are allowed only to family members, and second, they can only be transferred as gifts, not in exchange for money:
11.3 Members must not require or receive any consideration (in the form of a payment or otherwise) for any transfer to an Eligible Family Member.
While you're unlikely to get busted for casual buddy transfers, if the person offering to sell you points does this on a habitual basis, they may well be caught by an automated sweep looking for (say) people "donating" to over 10 "family members". And if they are caught, as their customer you also stand to lose your points or your membership:
8.1 If a Member has committed a material breach of any of the Terms and Conditions or has failed to pay any money due under Qantas Frequent Flyer or The Qantas Club by the due date, whether intentionally or otherwise, then Qantas may do any one or more of the following: (a) suspend or terminate the Member's Membership and/or the right of the Member to use the Card; (b) reverse or cancel the Member's Points or any part thereof; or (c) cancel or refuse to honour any Awards (including ticketed Award Flights), Benefits or both, that have been redeemed by or provided to the Member.
