Cafe Locked Out Live from Mt Isa with Luke Dan and Jeremy

I met Luke White in Canberra where he did a interview with his son Dan that went a little viral.
I also took an image of them both which ended up on the posters of Charlotte and the rear of Sandi. Now after 73 days from Melbourne and around 17 thousand kms, we have arrived at Luke's farm.
So who is the man that became, with his son, the face of Charlotte and the Deplorables.
