If there is a branch of AWB , All World Bearings, in Perth give them a go - my local branch has the best staff, stock, range and prices, and they only deal in top quality brand name bearing, Fag, Nacchi, Timken, etc.
BMW have given themselves all sort of problems over the past using off brand Rumanian bearings - probably the only way to buy a sub standard bearing over the counter in Oz in to buy a OEM bearing.
The BMW chains that recently gave all the problems were non 0 ring Regina and marked, Made in Czechoslovakia and I dont think it would be easy to get any of that either.
