and students making the national debating team. In 2008, the school also began involvement with the UN Youth Australia's Thant-Evatt Trophy – a model United Nations Security Council competition – two teams reached the state finals in that year.

Both are in the form of ties, with a design consisting of the standard MHS tie's stripes and a unicorn at the bottom for Half Colours; and the tie stripe alternating with unicorns for Full Colours. The Unicorns on Sport Colours ties are coloured gold; the ones on Service Colours are silver. In addition to the tie, Full Colours recipients as well as holders of some leadership positions can have their blazer emblazoned with their award or position. Position titles are emblazoned above the school emblem on the blazer pocket whilst award titles are emblazoned below. A system of badges is also employed at Melbourne High School (for house captains, SRC executives, class SRC representatives, high academic achievers, form captains and for various clubs). The Melbourne High School Speech Night features the awarding of various prizes to particular students for performance in academic subjects, co-curricular achievements or sporting feats. The academic prizes are determined by using data delivered through internal testing of VCE students. There is one academic prize for every subject, as well as a prize for Pure Science and scientific enquiry. The sporting prizes are chosen by the heads of a particular sport to reward the individual deemed to have made the greatest contribution to that sport during their time at Melbourne High. The co-curricular prizes are similarly chosen. In addition, there are prizes for 'Best All-rounder' and 'Sports Champion'. Brother and sister schools Melbourne High maintains close ties with its counterpart the Mac.Robertson Girls' High School. Each year the schools join
