When I was instructing at Jandakot a long time ago, it was suggested by CASA (CAA back then) examiners that if the aircraft ahead of us did a long downwind we should "go around from base".
The circuits had been getting very long so I tried it a couple of times one day. I advised the tower "going around from base" and flew a level base then an upwind. On downwind I called for a touch and go, to which Mardy in the the tower said "make a full stop landing and vacate the runway".
I never saw my student again. The tower put in an incident report and when CASA got hold of it they rang the Aero Club to find out who the instructor was to congratulate me.
I never did that again.
