Aerobatics should be a part of the PPL syllabus (but never will be!) And it's not just for fun. It gives you the confidence that you can recover the aircraft from any attitude. They also give you the confidence to manouvre the aircraft in a smooth positive way.
A mate of mine did his PPL at a Bankstown school with aerobatics as part of 'their' syllabus. The difference between his and my flying skills with around the same hours were stark
Find the money somehow to do aerobatics as soon as you can
Good Luck
