Leaky oil filter - why?

Have an annoying oil leak which i have tracked down to be the oil filter.
There was oil and crap all through the engine bay (pretty thick too) when i got the GQ and assumed that the sump needed tensioning.
Anyway, did an oil and filter change and cleaned it all up only to find that it is the oil filter that is leaking and not the sump.
Going by the massive amount of oil in the bay previous, im going to assume the old filter was leaking as well as the new one.
Now, the filter is on properly and tight - ive done filters many times before and this one was no different - so why is it leaking?
Is there something missing from the block like a filter extension or something?
The seal on the filter is good so i can only assume that there is something missing.
You can see a bolt hole for something under the filter, however, im not sure if there is or isnt one above it.
The engine is a TB42 carby/auto.
Any ideas?

Rip it off, make sure you wipe the mounting surface on the engine shmick clean. Then a light smear of oil on the new filter gasket and remount a new filter. Also spin till it seats and then just a half turn and your done. :)

Over time gaskets, orings etc get hard and perish, which in turn leads to leaking in some cases.
