Timboon police Leading Senior Constable Glenn McDuff said a vehicle registered to New South Wales was intercepted by Port Campbell police on Sunday.

"It was discovered that the driver and his passenger had travelled down from Sydney for the Easter weekend in a hire car," he said.

"They had arranged accommodation in Melbourne and decided Easter Sunday would be a good day to do a bit of sightseeing, which is clearly in breach of the COVID-19 'stay at home' restrictions."

The pair were both issued with fines totalling $3304.

It is understood the Melbourne accommodation business is under investigation for taking the booking on Friday whilst the people were still at their home in Sydney.

Leading Senior Constable McDuff said police also intercepted four young men travelling in one vehicle through Scotts Creek on Sunday.

He said the four men from Cobden did not have a valid reasoning for travelling.

"They had an excuse but it wasn't relevant so they were also fined $1652 each and sent on their way," he said.

"Police are reminding everyone that unessential travel is restricted in these times of a state of emergency and that the provisions of 'stay at home regulations' will be enforced."

Leading Senior Constable McDuff said police had received a number of reports of people's neighbours and friends failing to adhere to the rules.

"Several alleged parties have been investigated in the Corangamite area and people are reporting Facebook posts relating to people travelling or disobeying the rules," he said.

"It's a timely reminder that under these restrictions, you must stay home, you can't have parties and you can't have friends visiting unless it is in accordance with the government's guidelines."

Warrnambool police Sergeant Martin Flannery said members from the highway patrol unit intercepted two unrelated car loads of people on the Great Ocean Road on Friday.

"Both cars had occupants who lived in Melbourne, who said they were travelling on the Great Ocean Road for the long weekend," Sergeant Flannery said.

"That is not an essential reason to be travelling. It was obvious and blatant and they knew what they were doing was wrong."

They were issued with fines and told to go home.

South-west councillors and MPs last week called for roadblocks along the Great Ocean Road ahead of long weekend.

But that was ruled out by Police Minister Lisa Neville who said such a course of action was not backed by health advice.

A police statement issued Saturday morning said in the 24 hours to 11pm Friday night, officers working on Operation Sentinel had issued 183 fines while conducting 893 spot checks at homes, businesses and non-essential services.

Police issued only 98 fines during a similar period on Thursday, 78 on Wednesday and 114 on Tuesday.

Sergeant Flannery said there had been a number of calls in relation to breaches of the COVID-19 restrictions.

The social-distancing and isolation restrictions apply to visits to the beach, going interstate, holding large gatherings and attending church services.

"We are getting calls and we thank the public very much for assisting with that," he said.

"Upon attending a job, each set of circumstances are assessed and we determine whether it is necessary to issue a warning or a fine.

"If anyone wishes to report a breach of the rules, they can ring the police assistance line on 131 444."

Hamilton police Sergeant Ash Rawlings said officers had handed out fines to people who came to police attention through issues unrelated to the virus.

On Saturday, two South Australian men were arrested and charged over an alleged bungled attempt to traffick drugs into Victoria.

Police allege they attempted to disguise their vehicle with Victorian registration plates.

The two Mt Gambier men, aged 39 and 26, were intercepted in Hamilton, issued with COVID-19 fines and charged with drug trafficking.

Local police will continue to Operation Sentinel and Operation Nexus for the remainder of the long weekend.
