If anyone is looking for a comprehensive metric and imperial socket set, there is a good 64 piece Sidchrome one See it here http://www.sidchrome.com.au/products/64-piece-14-38-12-drive-socket-set- that is priced at $270 or thereabouts at Total Tools. Supercheap have them for $149, I got one this morning and it goes from very small 1/4" drive sockets up to quite large 1/2" drive sockets and also includes 3/8" drive stuff in the middle. Also has both sizes of spark plug socket. It has a big 1/2" breaker bar and the 1/2" drive metric sockets will fit my rear axle nuts. Not sure how long they'll have them at this price. I hope this is useful to someone.
