Brealey studied at Melbourne University, where he made his first amateur films around the age of 20. He was a member of the Melbourne University Film society and was a speaker at the Eisenstein Weekend organised by the WEA Film Study Group in October 1963. He began his directing career in television in the 1960s with the Australian Broadcasting Commission, where he worked for approximately eight years. His notable credits there include Australia's first science fiction TV series The Stranger and the 1965 TV miniseries adaptation of the George Johnston novel My Brother Jack. He wrote and directed a satire 'Say Bow Wow'. He directed three films for the Intertel series on Japan, Israel, and Malta.
He had a brief exchange visit with Universal Pictures in 1968, and in 1969 head of production Richard Mason approached him to join the Commonwealth Film Unit as a documentary film producer. His credits include the AFI Award-winning documentary short Bullocky and the three-part 'omnibus' film Three To Go, which includes segments by emerging directors Peter Weir and Brian Hannett.
