The structural integrity of the solid propellant grain after either an oxidizer or something inert flows through at operational engine pressure level in a large hybrid engine hasn't been tested much.Big chunks of the grain breaking off might obstruct the engine exhaust flow and cause an over pressure event inside the engine casing, if the propellant grain structural integrity fails after a previous oxidizer or inert substance flow through a large hybrid engine.
Beautiful day for putting up our 24m-tall fluids tower, which forms part of the ground support infrastructure for our maiden #Eris rocket launch at the Bowen Orbital Spaceport later this year! #BOS #behindthescenes #TestFlight1(Expected 🚀 date is now no earlier than Q4 2023.)

Launch is not coming nearer, schedule is humbug.

This has moved out by 6+ months, was supposed to be April 2023 (i.e. now). Do they have enough cash to go the distance if it slips again into 2024, adding approx. a full year of extra cost?
If you include Queensland taxpayer's funds, then yep they've plenty of cash to wait it out with and if Adam's past performance is anything to go on, would have little trouble getting more.
Their biggest hurdle always was, and still is, whether they'll get approval to launch anything over both the Great Barrier Reef (one of the natural wonders of the world) and one of Australia's busiest shipping lanes. Perhaps they should do a deal with Southern Launch instead?
Probability of successful maiden launch is very low. No startup has yet succeeded.
Tianlong-2 succeeded on 2 April and that was their maiden launch. But yes, it's incredibly rare and they were the first to do it (to my knowledge).

Engines from Russian with ARJ modifying them. Booster from Pivdenmash Ukraine and US from ATK.

Thanks to @theprojecttv for sharing our founders' story…and a special shoutout to all our fellow founders in the Aussie Space industry for daring to dream, and for having the courage, grit & determination to make it happen here in Australia. 💪🚀 ✨
Adam and James Gilmour grew up dreaming of being astronauts, and they might be about to make their dream a reality as their first homegrown rocket is being readied for launch.
Let’s reach for the stars, Australia 🚀You’re looking at the first Australian made rocket that will attempt orbital space launch.Gilmour Space Technologies started in Queensland as just two brothers, and they now employ almost 200 people.
Their hybrid rocket engine technology is the first in the world to use a combination of solid and liquid propellants.
It's truly an Australian manufacturing success story, and we want more of them. That's why our National Reconstruction Fund backs local manufacturing, including in the space industry.
And our Industry Growth Program in last week’s budget helps turn ideas into success stories. We’re backing more out of this world innovation, right here in Australia.
Did they share any information on if/when they might attempt launch?
