The ibises are usually located on the coast, by a beach where humans hang out. In Queensland, the council typically provide free BBQ facilities to cook your lunch. It’s often a great experience. The free BBQs are electric and on a timer, with a flat grill. I’m guessing this is the type of BBQ the hapless steak was stolen from.

Many NSW beach BBQs are gas AFAIK. I guess this is because buried high voltage infrastructure costs more to install to remote locations than an occasional gas bottle change.

Yes, I understand that. I don't think I've ever seen an Aussie with a grill that has a lid though? It's all flat grills.

The LPG BBQ on our back deck has a lid, and our setup is very common. (Keep in mind when we say “BBQ” we usually mean grilling, which is not what many Americans would call “BBQ”.)

If you go to Bunnings and look for a BBQ, heaps of them have lids.

Almost all of the barbecues you can buy now at Bunnings or Barbecues Galore (probably the two biggest Australian retailers for barbecues by far), have lids/hoods.

Most backyard grills will have them. It's just culturally people use the public parks and facilities a lot

I do, but I've had snags taken by kookaburras just trying to move them onto a plate before taking them inside.
