No problem. Here's what I think of these programs (note, just my opinion):
Swinburne: This is a program for people to develop interest in astronomy, but it is not going to help you get into an astrophysics PhD program. The description says, "It equips students with an overall understanding of modern astronomy, rather than training as a professional astronomer", and looking at the coursework, I see that this is pretty much an undergraduate astronomy major (or minor). It doesn't have any research components that would be useful to help you get towards a PhD program. It will also cost you 24,000 AUD total, so perhaps a better route would be a US undergraduate program. The program outcomes mention that it would be great for people who want to do work such as science/astronomy research communication, rather than research work itself. Based on your career goals, I don't think this is the right program for you.
USQ: This one is a little closer to your goals than the first program. It has a one year long research component, which is nice, but I am not sure how effective this will be to do online without in-person interactions with other scholars and your advisor. It costs 20,000 AUD per year for 2 years so it's not cheap either! I would say that if you are going to do an online program, find one like this one in the USA.
However, with that said, since you say that you want to be a researcher then you really will not get much value out of these online programs. For both of them, you see phrases like "Many graduates use this qualification to begin or enhance opportunities in teaching, working in observatories, science centres and museums, and science/astronomy education, public outreach and communication positions" and "Designed for those already in an educational or science communication career, you will undertake a professional development component in science, as well as gain a specialist foundation relevant for further research". These phrases, to me, suggest that the programs are more geared towards people working towards careers outside of astronomy research but need to have some sort of in-depth knowledge about astronomy in order to do their jobs. So, these types of programs, I think, are better for people who want to do things like work in planetariums, specialize in astronomical science journalism, teach astronomy, etc.
I think something like the Augusta program is going to help you a lot more towards a PhD program than these online MSc programs. I understand that it doesn't feel fun to stay at the "undergrad" level, but as I wrote above, the two MSc programs you mention are very similar to the type of coursework you would do as an undergrad in astronomy. There's no sense paying a ton more money for essentially the same stuff.
However, before you sign up for Augusta, I think it's worth thinking further about your plans. You say you want to be a researcher, but have you had much research experience in the past? I don't mean to doubt your dreams, but it wouldn't be great to invest a ton of time and money into this path only to find out you don't actually like it. If you have already considered all of this, sorry for assuming otherwise! Then, I think you should think one step ahead: first, figure out what PhD programs you might want to apply to (i.e. know your goal). Find out what kind of qualifications you might need in order to get into their program. You can email or call them and tell them about your undergrad experience and whether or not they would want you to actually enroll in a new undergrad program or just take the undergrad physics/astro courses.
Then, you should also talk to Augusta. Since you already have a CS undergrad degree, would they award you another bachelor's degree? Would they do so while waiving the "breadth" and elective courses so that maybe you can finish in just 2-3 years? I think your best path towards a PhD is to 1) get formal training in physics/astro (maybe you already have this if you chose lots of electives in physics during undergrad) and 2) be physically present at a brick-and-mortar school so that you can interact with researchers, and maybe have a chance to do some research too. The second one might be harder at Augusta, but if you are willing to apply for summer research positions such as REUs and be away for something like 10 weeks, then it could really help. Georgia Tech has a pretty decent program with hopefully lots of opportunities---it is probably too far to commute for school, but living in Atlanta for 10 weeks or a summer term might be doable? That's up to you to decide though.
Finally, if you want to know more about what it's like to be an astronomer, what it's like to be a PhD student in this field, and what applying for jobs etc. is like afterwards, I'd be happy to chat with you. Send me a PM
I just finished my PhD and started a postdoc research position.
