Funny as the moving Australia act was, I'm not sure that the navy is above such tactics themselves.
I seem to remember an inside documentry of the SDR on BBC2 in around 1998 where the naval chappies were justifying the building of new aircraft carriers to some senior ministers. Two of their arguments were
a) you can close down a land based airfield just by driving a land rover into the middle of the runway.
and
b) any given attack on an aircraft carrier only has a ten percent chance of sinking the carrier.
The counter arguments of a) move the land rover, and b) attack ten times, never seemed to come up!
