A man who filmed himself mowing down emus in victoria’s mallee district has had his sentence reduced. 

The man was originally charged with 42 days in jail and fined $800 for driving through the mob of emus last year. 

His sentence has been reduced to just 21 days in jail and a 9 month community corrections order including 100 hours of unpaid work. 

In his County Court appeal on Thursday, Macdonald's barrister Jacqualyn Turfrey argued he was a young man with no criminal history who voluntarily helped out farmers in his isolated community.
