The Department of Defence requests feedback on a proposal to amend the hours of activity of Restricted Area R768A Mt Stuart.
Defence has identified an opportunity to optimise the activation arrangements of Restricted Area R768A Mt Stuart.
The current DAH entry publishes R768A as active seven days per week: DLY 2100-1200 EXC PH or as amended by NOTAM. Review of operational usage indicates hazardous activities requiring activation of R768A occur predominantly during the Monday to Friday period, with weekend activity occurring infrequently.
Current arrangements therefore do not accurately reflect routine operational requirements and require ongoing administrative intervention to maximise weekend access when the airspace is not required.

The Department of Defence requests feedback on a proposal to amend the hours of activity of Restricted Area R768A Mt Stuart.
Defence proposes to amend the hours of activity for R768A Mt Stuart from:
DLY 2100-1200 EXC PH or as amended by NOTAM
to:
MON-FRI 2100-1200 EXC PH or as amended by NOTAM.
No changes are proposed to: status, activity, lateral limits, vertical limits, controlling authority, or activation by NOTAM.
The proposal changes only the routine activation arrangements for R768A and does not alter the physical dimensions or operating characteristics of the restricted area.
Assessment undertaken during proposal development identified:
• no impact to published ATS routes;
• no impact to published VFR routes;
• no impact to instrument flight procedures;
• no impact to aerodrome operations; and
• increased availability of airspace during weekends when hazardous Defence activities are not routinely conducted.
Defence considers that the proposal will improve alignment between published airspace information and operational usage while increasing access opportunities for other airspace users.
Feedback Sought
Defence particularly welcomes feedback on:
• Aviation safety implications;
• Operational impacts to local airspace users;
• Impacts to general aviation, recreational aviation or flight training activities; and
• Any local operating considerations requiring further assessment.
The proposed amendment represents an airspace optimisation initiative that reduces routine activation periods while maintaining existing aviation safety protections. Defence will consider all feedback received prior to finalisation of the Airspace Change Proposal and submission to CASA.
AvSEF members are invited to provide feedback by email to DOTAM SO2AIR at dotam.air@defence.gov.au by close of business 26 Nov 2026. Feedback received will be provided to CASA Office of Airspace Regulation as part of the Airspace Change Proposal.
