Beware Dick Bashers
Dick really has a bee in his bonnet. It's almost like he's on a wind up mission. And becoming increasingly abusive with his opinion of "the military people in Canberra" - almost slanderous one might say.
I do believe it was Dick, though, who allegedly invested close to half the Australian average annual wage in order to uncover the identity of a dick-bashing ppruner. So beware folks.... dick-bashing is not without its consequences. But I digress

Without knowing all the ins and outs of WLM, I do believe TWR owns the circuit area overland under VMC, with this airspace taken back by approach when instrument recoveries are required due weather. So you are incorrect in your assumption that TWR doesn't own any airspace - it's just not the bit that interests you.
