I'm assuming you haven't come from a medical imaging background so I can tell you this much (from my research - again haven't experienced this first hand but have dug into every forum known to man and asked people I know in the field)
- Sonography is in really high demand but the amount of traineeship spots are SOOO limited (seems a bit backwards, it's more of a cycle of 'we need more sonographers' but ' training someone into sonography is too expensive in terms of $ and time')
- I've heard that about a third of sonographers don't come from a medical imaging background (e.g. nurses) and took up training positions at their place of work in order to complete the clinical placement hours required by the degree (graduate diploma).
- I know someone who was a pharmacist before she did sonography. She did the undergrad at CQU and said it was good - but that was back in the day. Nowadays, the majority of reviews are veryyy negative and the uni is finding it hard to find student placements as well
- Can't say whether the wsu degree is good or not but I like my uni. If you were also considering general sonography, there are diploma courses at Canberra and Uni of South Australia - both are completely online. Canberra do offer some introductory training at the start of the diploma if you're having trouble finding placement (not compulsory)
- With the online graduate diplomas, you are expected to find your own clinical placement which is the hard part. Hence many people do radiography to get into the medical imaging field and then take up any sonography training position their employer may offer. Employers prefer to train someone already working with them as they know their investment of time/money will be a good one
- There are some intensive courses (search ASMI in sydney, integrated ultrasound education in perth) out there that could help you get your foot in the door and hopefully land the traineeship that you are expected to find by yourself - these are superrr expensive (upwards of $35000) but it's a good investment in the long run if sonography is where you want to be especially since you'll likely start getting paid as a sonographer earlier
- AIHE do a graduate diploma aswell (based St Leonard's Sydney) and they have their own training facilities onsite before they put you into a clinical placement. I have heard that many dislike the course though and the placement they 'guarantee' isn't really guaranteed
- Cardiac sonography I believe pays more than general sonography and is more specialised but other than that I don't know too much
I know I just blurted out a heap of information that isn't specific to cardiac sonography but I hope it helps
I know it took me weeks to find all this information so hopefully this is a fair summary of what information there is out there to help others looking into sonography
