Mr Price said he had campaigned for improved services for more than four years but his complaints had been ignored.

"It has all been falling on deaf ears," he said.

"I want to call on all Wimmera people, community leaders - business leaders, councillors, emergency service agencies and politicians - to speak out and make a very clear message. If we want a safer environment to live in and a developing and expanding tourism industry, we need to address this issue."

Mr Price said while communications problems had caused issues with customer bookings for his own business, he was most concerned with the safety of people in the Grampians.

"A quick response is the answer to fire suppression," he said.

"There have been a few examples at Mackenzie Falls where it has taken 45 minutes to ring in an emergency and then it takes another 30 minutes for services to respond and get there. It's not just fires, it could be any emergency such as a heart attack or a rock climbing fall."

Mr Price said the lack of communication was having a significant effect on the tourism industry in the Grampians.

"After the 2006 bushfires the antidotes to a decline in tourism were to market and promote, whereas really we need infrastructure changes," he said.

"We have a huge number of visitors coming through our region. Some of our clients are from Australia and some are international but they are all demanding good communication facilities.

"We've been trying to invest in technology because guests expect phone and internet services. I'm promoting my business but we're losing customers because of poor communication services."

Mr Price said the Grampians tourism industry still had not recovered from the declared catastrophic day last week and the industry was also struggling since the 2006 Grampians bushfires.
