Finalising the TLGprocess

#TuneUp2011

>Process finished once TLG have considered all issues raised in discussion papers

>Duration of each TLG may be different dependant on complexity of issues considered

>Aim is to achieve consensus on issues

>Final decision rests with the ACMA

>Publish outcomes (i.e. final versions of TLG papers)

>Target is to finalise both TLGs by the end of 2011 for input into draft Marketing Plan planned to be released in February 2012

Post TLG process

#TuneUp2011

>ACMA will create/amend legislative instruments to reflect outcomes of TLG

>Marketing Plan
