THREE people who were working on the Huntly-Goornong track upgrade have tested positive to COVID-19.
COVID commander Jeroen Weimar said the cases were connected to the V/Line contractor who returned a positive test on Thursday.
Mr Weimar said the new cases were people who lived in different parts of regional Victoria but worked on the upgrade.
The new Bendigo exposure sites were related to those positive cases, Mr Weimar said.
Bendigo Health on Friday confirmed more than 100 primary close contacts were isolating after the contractor returned a positive case.
Mr Weimar said there were 30 new coronavirus cases recorded in regional Victoria on Saturday.
The COVID commander said a third of those cases were workplace incursions from people who were living in regional Victoria but working in metropolitan Melbourne.
