Connecting unconnected tickets

[MG1]

Hello,
I'm not sure if this mentioned somewhere else (please merge thread if that would be more appropriate).

I've got what would normally be a connecting flight from USA, through DOH, to Australia but purchased on separate points tickets (separate points currencies) with a transit time of 3 hours. I've looked into connecting these but I appear to not be able to. I assume this means that I'll need to enter Qatar by going through the customs line (and therefore requiring entry documents, such as a visa), collect my luggage, then re-check the luggage back onto the next flight. Will three hours between flights be enough for this?
(I'm concerned that if the first flight is delayed/cancelled, or the customs line is super long in DOH, I'm at risk of missing my flight back to Aus.)

As both flights are with QR, is it possible for the check-in desk staff member to check my luggage all the way through to Australia, meaning that I wouldn't need to "enter" Qatar but just stay in the transit area?

I've looked into moving the second one to a later date but no availability (maybe there'll be more closer to the date of travel (July))?
I've tried to see if it's possible to enter via a different Australian city but I appear to only be able to change the date. I suppose I could attempt cancelling the ticket, wait for the points to reach my account, then re-book via a different Australian city and hope that it doesn't get nabbed in the meantime.

What are your thoughts?

(I know that I should've allowed a day or two in-between but this was a rookie mistake that I'll learn from for next time.)

From a FT thread QR interline bags QR to QR on separate PNR's. Was not able to find that info on the QR web site. But still a risk if an inexperienced checkin agent. Ask for a supervisor if needed and be at airport early (not be the last to check in for that flight)

As the first fight is USA - DOH they may require you have the full documentation for entry into Qatar. Best to check now.

With separate tickets all the risk is with you. The 2nd flight will close X minutes before scheduled departure, so you do not have 3:00hrs.

@Mwenenzi, thank you for your response.
The forum that you linked to did seem to indicate that QR may be willing to connect the tickets if you're in DOH.
Having read this, I could try getting the tickets joined on the way to the USA (also with QR via DOH (on a points flight) but this one is on a connected flight).

I took a look on many websites (SmarTraveller, Sherpa, Visit Qatar, QR) with regards to entry requirements and it seems all that Australian citizens need is a valid passport (6 months) and proof of an onward connection.

I understand that the connection will be closer to 2hrs, due to check-in closing time, which is why I'm looking at my options prior to then. Next time, I'll allow more time (i.e. a day or two) in-between. It's all a learning experience.

I'm grateful that I've got communities like this to ask advice of fellow travellers.
