I'm sorry you're suffering like this.
Do you know why they formed in the first place? It's true surgery can be a temporary solution because they can reform from the trauma of operating but their cause may also be a factor here.
Unfortunately, I cannot help with a surgeon in Australia but I think you need to persist with different consultants/surgeons for a long term management plan.
In reality, you might be looking at long term management of the adhesions rather than a simple solution and this will take trial and error.
Are you under the care of a dietician? They can help find an ongoing nutrition plan thats easier for you to follow and helps with long term management.
With regards to pain, have a look at the Curable app which helps people manage chronic debilitating pain. If you suffer from bowel pain then you might find things like peppermint tea can help ease it, or resting your bowel for a day - but you really need the guidance of medical professionals here and i think you're looking at a cross-discipline team to help.
I know people living with similar problems from adhesions and it's not an easy thing to manage but through trial and error they've found a way that works for them.
I also know first hand the toll chronic pain takes on a person which is why I think you'll benefit from nonsurgical approaches too.
It sounds like your care needs to be overseen by someone with experience of this problem as a result of it's initial cause. Eg - has the scarring developed from an infection? Or should that supervisory role be undertaken by a pain specialist?
I understand your desperation, you might find that you gain better traction with your medical team if you demonstrate willing to explore other management routes because their reluctance to operate again is valid. If alternative approaches don't work for you then you might find they're open to considering some sort of surgery again(?)
I wish you the best of luck - don't give up, there are ways to help you with this and there is light at the end of the tunnel, you just need to find the right experts
