Just extend, far easier.

But first time border run you would be extremely unlikely to have problems

NO, Deferred indefinitely at this stage so check again at end of April

It's very difficult to say.

But it's far less likely Thailand immigration will ask about onwards travel but not sure on the airline...

I have flown 1 way in the past without any problems..

Just on another note regarding your travel..

Make sure you have a visa for Vietnam BEFORE you travel as there is NO visa on arrival for Australian passport into Vietnam.

You must have a visa before you either fly or attempt to enter by land.

And be aware buying last minute flights back to Australia can be quite expensive as well if you are planning to do that..

Australian passport you get free 60 days visa exemption entry to Thailand.

Nothing required, just show up at immigration with your passport.

Electronic Travel Authorization..

When it's finally implemented it's going to be an app or website for you to advise Thailand immigration of your visit in the near future..

Name, passport number, dates etc ....

Countries like Singapore and the Philippines already have an ETA in place so it's not a new idea..

The USA has had a similar system in place for years for foreign visitors..

It's a way to screen visitors before they arrive and reduce the number of turn backs at the border who may have criminal records or overstay history in Thailand...

If your ETA isn't approved then don't bother going to Thailand and the airlines are likely to check ETA approval before you board the flight.

Forget about the ETA as it's been postponed indefinitely...wait for official Thailand government information and ignore old information on the internet....

Make sure you check your visa requirements for Vietnam BEFORE you travel

Your passport must have at least 6 months left before it expires at the time of entry..

It's unlikely the airline will allow your friend to board the flight on that old passport.

You don't mention your friends passport country?

But some countries allow express passport processing for an additional fee..

And if they have a passport from a country that requires a visa BEFORE you fly then that also could be a problem arranging a last minute visa with limited time..

If they have a visa already on the old passport number that will not be valid anymore

who knows really it's a gamble but maybe the smaller airports could be better

No
