The loss of communications procedure for an airport I use has this, in part, to say;
COMMUNICATIONS FAILURE: PROCEDURE IN IMC
IF ABLE CONTACT BRISBANE ATC ON TELEPHONE (07) 3866-3694
Apart from giving them a call once you're on the ground the only other option is to use you mobile phone airborne. The regulator must feel there is little danger from mobile phones to have this as the lost comms procedure.
The above statement is on the local Australian AIP and also the Jeppe plates.
