The RAAF have a line squadron flying a 4 ship Hornet display for the big shows and very good it is too.
The first part of the display is formation work, reminds me of the old French Mirage F1 and Jag 2 ships displays - very slow but very close formation and impressive to watch
The second half of the display is a role demo with lots of high speed passes and flash bangs - again very impressive and a good contrast to the earlier formation work.
Of course the RAAF also have the Roulettes - 6 PC-9s - I think but don't know that they are part timers.
Also both the Hornet and Super Hornet have solo displays.
Not bad for a far smaller airforce than the RAF.
