Again I ask;

Please explain to me how the Indonesians can refuse entry to an
Indonesian vessel with Indonesian crew ?

Why is it that no one who is adament that the boats cannot be
turned back because the Indonesians will refuse entry, cannot show why.

Bazz, I wrote: "Furthermore, if we put refugees on our boats and try to return them to Indonesia they won't be accepted."

i.e. should boat-people scuttle their boats and be picked up by our navy they will not be accepted by Indonesia should Australia wish to return them. The Indonesians have said this.

The answer to your question/request, "Please explain to me how the Indonesians can refuse entry to an Indonesian vessel with Indonesian crew?" is they can't and don't.

Sorry not to have addressed this before. I'm not adamant that boats "can't" be turned back, that was happening a decade ago. I'm adamant that they "shouldn't" be turned back again and that the Malaysian swap should be given the chance to work.

The Greens and the Coalition are adamant that it shouldn't be given the chance for different reasons, the former because of flawed, blind principle and sentimentality and the latter because for the cynically astute political reason to get elected.

Hmmm, even if they are rescued by our naval ships, I think the Navy
would be required to return them to their port of departure, especially
if they were picked up in the Indonesian rescue zone.
I suspect, but am not certain that the zone extends almost to Christmas Island.
It might only take a more determined government to point out to
Indonesia their responsibilty for Indonesian vessels and its passengers.

If they are rescued, there is nothing stopping them being taken directly to Nauru, even now.
