The network included routes to Armidale, Barcaldine, Biloela, Blackwater, Brisbane, Canberra, Coffs Harbour, Coolangatta, Cooma, Grafton, Glen Innes, Hervey Bay, Kempsey, Maroochydore, Maryborough, Melbourne, Newcastle, Port Macquarie, Roma, Sydney, Taree and Tamworth.

Impulse used the aircraft to pioneer non-stop services between Newcastle and Melbourne but was soon met with competition from Qantas who utilised the much larger BAe 146 on the route.

Services initially operated between Sydney and Melbourne and quickly expanded to include Brisbane, Newcastle and Hobart.

The new low cost entrants injected competition into the long-lived duopoly between Qantas and Ansett, arguably contributing to the downfall of the latter.

In April 2003, following a long running investigation by the Australian Securities & Investments Commission, Rene Rivkin was found guilty of insider trading after having purchased 50,000 Qantas shares which resulted in a $346,000 profit.

He bought these shares on behalf of Rivkin Investments on 24 April 2001, just hours after speaking to the executive chairman of Impulse, Gerry McGowan.
