Well, with the exception of a torque wrench, balancer puller, and a piston ring compressor - all you need are basic hand tools.

I have a decent set of vernier calipers I use for bearing journals and deck height measurements; they're close enough and way cheaper than a good micrometer, especially since you'll probably need more than one size micrometer. If you want to check the bore diameters to see if they're still within spec for roundness, taper, etc., then you'll also need an ID micrometer. I got a cheap set at either Home Depot or Harbor Freight (not sure what your equivalent is in the land of Oz); they're tricky to use but all they have to do is hold a measurement that you then read with calipers or an OD mic. If you know you're having the cylinders bored anyway then you won't need these.

If you plan to assemble new pistons to the connecting rods yourself, you'll need a press. I got a 12-ton hydraulic press at HF for about $130 that hasn't broken yet, but if you only have to do this once then it'll probably be cheaper to have the machine shop do it.

Take your time and use the search function on this site liberally. Don't be afraid to ask questions.

I second the Factory service manual. Dont forget piston ring expander, and an absolute must is plastigage for bearing clearances and feeler gauges for piston ring gap in my opinion. Good luck!
