Not answering your question, but I think it is likely that Esther TURNER who was transported to NSW in 1817 was related to Mary BOULTER.
Esther's convict records are 'light on' for information, as most are in that early period, and I cannot see anywhere that her marital status is mentioned so I don't know if TURNER was a maiden or married surname.
She was tried at Taunton on 30 March 1816 and received a sentence of 15 years for being in possession of forged bank notes. She was transported on the 'Lord Melville', arriving in Feb 1817. Her age on her indent is almost illegible but looks like either 30, 36 or 38.
Just a few months after arriving she applied to marry James SLADE (free by servitude, Duke of Portland, 1807).
She appears on the 1828 census with James SLADE, a shopkeeper, living at York Street in Sydney. Her age then is 37, but I think that is wishful thinking. I suspect that James was transported as James GREENSLADE and was also from Somerset. He appears to have ended up being quite well off. There is mention here in relation to a land sale of James GREENSLADE and Esther his wife.

In 1846, Esther thought she knew something about Mary BOULTER that was worth a bit of a gossip:
NOTICE - I hereby Caution Mrs. Esther Slade, of George-street, in the City of Sydney not to injure my character in future by reporting falsehoods, as I am determined to prosecute her hereafter according as the law directs.
MARY BOULTER.
Redfern, November 18. http://trove.nla.gov.au/ndp/del/article/12890135Esther died in 1853 and her burial record states her age as 74, so born c1779 which would tally with her being about 38 when transported and 12 years older than Mary. I think she was living with Mary at the time of her death:
Another inquest was held at the Three Tuns Tavern, on the body of Esther Slade, then lying dead in the infirmary. It appeared that the deceased was a very feeble person, about 75 years of age. She had been separated from her husband during the last three or four years, and resided with a family named Boulter, in George-street. Dr. MacEwan gave a description of the deceased, after her decease. The jury returned a verdict - Died from pre-existing disease.http://trove.nla.gov.au/ndp/del/article/60134968http://trove.nla.gov.au/ndp/del/article/12942655Debra
