You may already be aware of them, but there are records for what appears to be your Shea family in the Family Search database [https://www.familysearch.org]. ; If you create a (free) account there, you can find Hanorah/Honora under ID number LR88-MR7, and can access the records for the others easily through that record, as you will see.
The records show Hanorah Coakley as being born in Macroom in 1791 and being buried in 1879 in The Oaks Cemetery Camden NSW. They show her husband as Thomas Shea, born in Macroom in 1786 and dying in 1820. No death location is given, but from your info that would presumably have been in Ireland, which would explain why he was not around when they were transported (and perhaps why they had to steal food).
Three children are indicated, born in these years: Daniel in 1811, Judith ("Mary") in 1818, and Patrick in 1820. Margaret is not shown, but perhaps she was not known to the people who created the records.
Patrick is shown as dying in Minnesota in the US in 1900. Since you don't have a record of him being transported, perhaps he stayed behind and then later emigrated to the US, and was not known to your branch of the family.
Daniel is shown as dying in the UK in 1879, and the records show a marriage and two children for him. If your Daniel died in Australia, then this info may have been added by someone in the UK by mistake, and may be for a different Shea family.
In each record, at the right hand side of the record you can see the screen names of those who have created or modified the record, and can send them private messages, so you might be able to get more info by contacting them (and perhaps also locate some relatives that way).
