Anyone Else Got One

I was polishing me van with me new Aldi Buffer that was better than I expected, I took a pick of this, has anyone else got one , any ideas what it is ?, here's a clue @Terrordales will probably know

 

Roo bar attachment point?

 

Close but no cigar

 

Koala net attachment point?

 

Its good but its not right

 

Looks like an old Lpg tank inlet.

Failing that I'm going bilge pump outlet.

 

No & No

 

Nesting box?

Squirrel nut depository?

 

No and YES!!!!! well done



Only joking ...NO

 

There's obviously a clue saying that @Terrordales will know, pointing to Australia. But my Australian van doesn't have this?

 

Mine must be posher!

 

Oh...never saw the clue bit....is it a pipe for the safe passage of snakes?

Some form of defusing device of kangaroo hormone so that skippy stays behind the van, not in front?

Something to do with barbecues?

 

Glory hole ?

 

Stern thruster?

 

This ?

 

The same yet not the same.....a didgeridoo holder?

 

Tinny recycling hole?

 

It is the mounting hole for the bottom of the roof rack access ladder?
