To install you will need to use some original textures, create the folder: texture.qantas, copy ALL textures from the original texture folder and place them into your newly created folder. Then simply unzip my textures into your PMDG 737-700 texture folder, make sure you select select 'Use Folder Names', overight the files when prompted, voila, you're done.
Now copy and paste the following into the aircraft.cfg file:
