Many thanks to one and all!
Found the following as well -
http://trove.nla.gov.au/ndp/del/article/12941046Gerry - 3 sons and 2 daughters - William Alfred (possibly born in Sydney, possibly born in London) Samuel Henry born in London, Sydney Collins born on the journey (James Giles died in Shoreditch Jun qtr 1851)
Georgiana Catherine born in Sydney (one other daughter recorded elsewhere as Sarah Ellen, born Sydney, but not present in 1851 census)
Ros - You have a record for William Alfred born in Sydney, 1848, 1851 census says born in London, one online tree says he was born in London, another says Sydney - take your pick! If parents plus just the 2 daughters (Georgiana and Sarah) came to England in 1848, I would perhaps say William was born in London, but there is a birth record in NSW in 1848?
It would seem that Alfred Toogood was involved in the Coventry riots, sent to Van Diemens Land in 1832.
He was assigned a new master, a Mr Raine, and in 1838 he was shipwrecked. Nine passengers, including Mr Raine drowned. Survivors walked six days into Twofold Bay. Alfred was then selected to walk overland to Sydney, which took him over 2 weeks.

He must have been pleased to see his brother arrive 10 years later. ''Publicans Records show William held Licenses for Rainbow Hotel, Rainbow Tavern,Toogoods Hotel, Rose and Crown, Golden Fleece Hotel & Masonic Hall. His first license was in 1839, several years before his Absolute Pardon in 1843.''
A fascinating family (see how easy it is to get side-tracked at this hobby!)
Thank you all again for your input
