For those not aware, New South Wales has a divided legal profession, Barristers and Solicitors. Some of the other Australian States have a fused profession where a person can be both at the same time. Not so in NSW where one has to be one or the other.
So what is the difference? Solicitors also appear in courts and tribunals but the higher the level of the court the more likely the appearances will be by barristers. Think GP's and specialists in the medical profession. Barristers mostly do court work (unkindly called "rent a mouth" by some) and give advice, both in conferences and by written opinions. Solicitors do the same but also carry out general office work, filing and service of documents, preparation of cases with the barrister and practice in fields that barristers don't: conveyancing, leasing, Wills and so on.
Barristers usually specialise in certain fields so that they become knowledgeable and expert in those areas. A solicitor engaging a barrister, whether for advice or for representation, is termed "briefing counsel".
In the higher courts barristers like to set themselves apart from the hoi polloi by wearing wigs and gowns, such that a day in the Supreme Court on mention and directions listing days (wall to wall barristers in the [pre-covid days) can often feel like one has been transported hundreds of years back in time.
I should not be too impolite since some barristers subscribe to Bytes and in that son Thomas is a member of the horsehair wig fraternity, specialising in criminal law.
Here is the tale of a less than successful barrister who ends up having to face a final judge . . .
