Career
She was an Australian Institute of Sport scholarship holder. Domestically, Avellino played for three Australian Commonwealth Bank Trophy teams, the Adelaide Ravens, Sydney Sandpipers and the Sydney Swifts. Avellino played for the Sting until 2007 when she retired to become the Southland Netball coach in the National Provincial Championships.
She has since been announced as the new Southern Steel co-coach and will work with former Otago Rebels coach and current New Zealand under 21 mentor Janine Southby.
They replace Robyn Broughton who had coached the Steel for the previous four seasons, and all ten years in the National Bank Cup with the Southern Sting. Avellino has also worked in New Zealand media.
She is a netball writer for The Southland Times, and worked for Sky Television as a commentator during the Australia and New Zealand Banking Group Championship from 2008-2011. She will give up the microphone in 2012 though, because of her Steel commitments.
