The road was closed in both directions between Hotham Heights and Harrietville after two buses became bogged about five kilometres from Mount Hotham on Sunday.

VicRoads announced the re-opening Monday morning and thanked motorists for their patience.

"Motorists should continue to use extreme caution and drive to the conditions," VicRoads said.

"When driving in snowy conditions, drivers should always carry snow chains and fit them if directed by authorities."

EARLIER: Extreme weather caused a number of roads closures in Victoria's alpine region on Sunday, but the rain has helped bolster farming outlooks in the southern Riverina.

Agronomist Tim Paramore, of Walla, said recent rains had been a big help to farmers but advised against being overly confident.

He said at this stage unless it was particularly strong, frost wasn't a huge concern.

"Everything looks tremendous, crops are growing, it's just a matter of if we can fluke a bit of rain in spring.. the potential yield is good but we need follow-up rain," he said.

Mr Paramore said his rain gauge recorded 14mm over Friday and Saturday, and a similar amount the week before, while a friend from Billabong received 27mm in one week recently.

"We're probably very lucky, you don't need to go far north to see its still very dry," he said.

"I was doing some deep soil testing, down to 60cm, at our property and it was dry at 30cm, the soil profile was not very wet. But it's no panic because you don't tend to use a lot of water in winter until the end of August.

"If we don't get rain by Henty [Machinery Field Days] then we know we're in trouble."

Mr Paramore said farmers should not get carried away just because there had been a decent amount of rain so far this season.

"[The Bureau of Meteorology] lower than average rainfall, there's about a 25 per cent chance of median rainfall, so my advice to people is to proceed with caution," he said.

"Don't get too carried away with fertiliser or big crops or extra stock. I'd advise caution over confidence."

Heavy snowfall caused the Great Alpine Road between Hotham Heights and Harrietville to close in both direction after two buses became bogged about 5 kilometres from Mt Hotham on Sunday.

Victoria Police said no one was injured but advised motorists to take care due to the extreme weather and expect delays when travelling via alpine roads.

Falls Creek received 56cm of snow across the five days from Thursday to Sunday, including 16cm overnight into Saturday.

Mt Hotham recorded about 30cm of snowfall on Thursday and Friday.

In Albury-Wodonga temperatures dropped to 0.8 degrees at 1am on Sunday, while 11.4mm of rain was recorded in the 24 hours to 9am on Saturday.
