Riverside high school is your best and closest option and is regarded as a good school around Launceston. Launceston being a smaller city gives you the advantage of most schools being within a 30 minute drive and there area few great schools to choose from. Personally I would go with Riverside due to it's good reputation. Trevallyn is a great suburb of launceston and I am sure you will love it if you make the move.
Hi, Riverside High School is the closet High School and is fantastic. Seeing as Trevallyn is so close to town and bus routes, there are also a number of Private high Schools which would be easy to reach.
Riverside High School is a fantastic school with a very good reputation. The great thing about Trevallyn is that it is still so close to Launceston so you have access a range of Private Schools as well. Trevallyn is a beautiful suburb so if that is where you want to live then rest assured you will find a great High school/Senior school close by.
The closest public school is Riverside High. However, many students travel from all suburbs of Launceston to attend the private schools - Launceston Church Grammar in Mowbray, Scotch Oakburn in East Launceston, and St Patrick's in Prospect. Bus services provided by the schools are very good and travel time is not long.
