This is a message is primarily for 'Megan in Australia'.
Are you still searching for resources on the 63rd regiment's deployment to Tasmania? If so, are you near a State Library or the National Library (NLA)? If you can go there and have lots of time
, the microfilms of the War Office (AJCP) are worth the effort and eye strain to trawl.
I have an interest in the 63rd regiment c1823-1834, when it was in Ireland/ England/ Portugal and then Tasmania. I too have looked at Macquarie Harbour, but transcribed information relevant to a Private Joseph McMahon - the sergeants are on another page and clearly marked as such. The filmed pages I refer to relate to (pay) musters, so you can most often read where the soldier was detached to.
There's also a book ['History of the Manchester Regiment', Wylly, HC (ed), London, Forster & Groom, 1923] in NLA which you could get through inter-library loan - I recommend it, if you're interested in the period before your sergeant got to Tasmania. The editor had little interest in the Tasmania deployment though.
There is also a lot of information about the Regiment's role in the so-called black or indigenous war of Oct 1830 - see also Trove* for that.
Did your sergeant get a pension (because of really long service or severe disability)? Try the Army pensioners' files online at (UK) National Archives. Good information there if your sergeant was entitled and the file itself has been filmed (I think you can pay for a copy or can access it on one of the subscription sites).
On another thread about the British Army, someone stated the first and last entries for a soldier in the regimental record are the best for genie-type information. The last worked for me (eg next of kin, birth place, enlistment date), but I can't access the first from Australia because it wasn't part of the AJCP filming.
Hope this helps
