The decision to cut the regular Tamworth-Sydney flights came as Virgin decided to reduce its domestic capacity by 90 per cent.

Along with Tamworth, Albury, Newcastle and Ballina Byron are amongst the regional centres on the list of suspended services.

"The Virgin Australia Group has confirmed a revised domestic schedule following the group's decision to extend domestic capacity reductions from 50 per cent to 90 per cent, including the suspension to Tigerair Australia domestic services effective immediately," a statement read.

"The group will continue to operate near daily services to 17 Australian destinations for the purpose of transporting essential services, critical freight and logistics.

"The group will temporarily suspend services to 19 Australian destinations from midnight March 27 to June 14, 2020."
