To the best of my knowledge Australia does not have any recon capable satellites of its own. It relies on Allied satellites, primarily US assets for this capability. If we want these areas surveyed we need to ask for it. Thankfully I suspect these are regions the US regularly looks at as it monitors the Chinese fleet closely.Does the ADF have satellites covering the northern approach choke points watching all transiting seaborne traffic?
Otherwise we use Tritons and P8s to monitor sea traffic around our coast.
Australian Defence doesn't even have its own comms satellites.
