I agree with Philidor, a very interesting post! you certainly know your engines!!!! Thanks!
Because of the fact the Qantas still use four aircraft of the type Boeing 747-438, powered by four RB211-524G/H-T three-shaft turbofans (fan diameter: 2.192,0 mm / 86,3 in; eng. architecture: 1F-7IPC-6HPC ^ 1HPT-1IPT-3LPT), rated at 269,56 kN / 27.488 kgf / 60.600 lbf, all the engines from the Boeing 747-438 - MSN 24354 / LN 731, reg. VH-OJA (test reg. N6046P), that first flew on 03. Jul 1989, were, as our jkkw has already said, removed and only the replaced engine No. 3 is under the VH-OJA´s wings now. Since this replaced engine is one of the engines that were used, as jkkw said, on one of the QF´s Boeing 747 aircraft series –200 and –300, it could be RB211-524B used on Boeing 747-238B(M), RB211-524C2 used on Boeing 747-238B or RB211-524D4 used on Boeing 747-238B(M), Boeing 747SP-38 and Boeing 747-338 aircraft.According to a post (see post #146) in the forum below, the engine is a RB221-524D4

There was also an engine installed at the engine 2 position and an additional engine that was waiting to be installed on the engine 1 position. The engine was fitted soon after I visited.

If anyone's interested, here's a comparison between the fan of the older RB221-524D4 (top pic) and the RB211-524G/H-T (although you can't see the fan itself too well due to it windmilling)
