Long Answer - Qantas club membership only gets you access to Qantas lounges and the contract business class lounges where Qantas flies its own aircraft. You also need to be flying on a QF or JQ flight number. The only exception to this is AA lounges in which you can access with either an AA or QF flight number.
BA in Prague use the Menzies lounge and if you want access to that you'll need to either be Gold/Plat with Qantas or the one world equivalent. The lounge is also a priority pass lounge if that helps.
Sorry if that's a bit to wordy and long but I hope if helps.
