G'day again..
Looked a bit closer - got my own answer..
Available in OZ is the Purolator L14610 Oil Filter (3.5" long) from
http://www.gimmecarparts.com.au/
( the L 14612 is identical to the OEM at 2.5" long )
I ordered 3 x L14610 , cost delivered $29.50 actual shelf price about $6.50 each.
I expect these are available in some of the auto shops but have not checked. They also fit a host of cars.
Now I WILL :-D change the filter each time I change the oil.
