Things have changed.
The high levels of unemployment amongst young doctors in the UK, and the exponential growth of private medical schools in Eastern Europe, Asia, the Caribbean and Africa means that there is a worldwide shortage of entry level and training jobs. Patients in the UK and Australia are reasonably unusual in being willing to be seen/operated on by SHOs. In systems where there is an underdeveloped public health system, people who pay expect to be seen by a consultant.
Australia, unlike the UK, gives priority to their own residents, so the plum jobs go to them. There is a tradition of hiring from the UK, and the Australians seem to like our training and language skills, so it used to be easy for Brits to pick up year-long contracts. Essentially working holidays after 7/8 years of slog. It is still reasonably easy to get work in rural areas or in A&E, but competition for more popular career-building experience in major cities is tighter. DD managed to land one, and was told that they had caried out a lot of background research, and that only a third of her peers will not be Australian residents. She expects that half of these will have already worked in Australia for a year or two, as you have to have been working in Australia for a set number of years before you can be considered for training.
The issue now is how you then get back. In the UK and because we do not give priority to UK residents, even locally employed jobs in hard-to-recruit places and unpopular specialities are attracting hundreds of applicants. (As well as opening up our job market to worldwide competition Boris gave expedited family settlement rights to many categories of health workers, which has proved a major pull factor and which is what the current parliamentary immigration debate is about.) There are already quite a few young doctors who went out in the last 2/3 years and are now struggling to get back. DD plans to see how the land lies and if she wants to return, will save so she can afford to take a gap year/Masters to allow time to prepare for UK specialist exams. Sadly the GMC do not automatically recognise Australian specialist training and it can take years to get "equivalence" sorted, during which time you can only work locum contracts in the UK, so training there is only worthwhile if you plan to stay.
All of which is a long way of saying that it all depends on how good Beth is. The "special status" may help a little, but unless he is really good, with good practical skills and great references, he will probably spend the next year on A&E night shifts or in the outback, and finding that he has few other options until he has enough years in to qualify for resident status. It is very likely that we won't see Beth again, but more because the NHS career path is f**ked rather than anything around trans or the case.
