Relationships Australia Tasmania's Gamblers Help counsellor Megan Booth said the support service wanted to see a reduction or total ban on the promotion of live odds.

``We see the impact on families and people at the other end,'' she said.

``We have concerns from watching sport, which is a family activity, we know that children and young people are being exposed at a young age to gambling, with the advertising of live odds.

``It's hard to measure the level of the problem but we know that 8 per cent of people have a problem with gambling, and another 15 per cent are at risk of having a problem.''

The ease of access to gambling websites and the pervasive nature of gambling advertisements during televised sports matches increased exposure, Ms Booth said, and meant people were often not fully aware of the potential for problems, as they were with poker machines, for example.

Anyone was at risk of problem gambling, she said, particularly those who had other problems in their lives.

Cricket Tasmania chief executive David Johnston said his organisation did not have any direct input into betting on the state's cricket matches, or any association with betting agencies.

``We have a lot of training for staff and our playing group about betting around cricket, and it's forbidden for any of our directors or players ot bet on any cricket at all,'' he said.

``From our point of view, betting is a social want and how people decide to bet is their decision.''

In the past, Cricket Tasmania had decided against allowing advertising for betting on matches, Mr Johnston said.

``Our reasoning was that we felt that we are very much promoting the game to all Tasmanians, and that includes young people,'' he said. ``We have people playing cricket from age 5 up to their teenage years, and we didn't feel it was appropriate to have our teams associated with that type of product.''

Football Federation of Tasmania chief executive John Boulous said while punters could bet online on the Victory state soccer league - and the Premier League beneath that - it was not supported by the FFT and bets could not be placed via the organisation's own website or in person at games.

``We have a code of conduct that says players and officials won't place bets on matches within the leagues they participate in, and we have sanctions in place under the national policy if they are found guilty, but we haven't been made aware of any instances,'' he said.

There were no cases where leagues or teams were sponsored by betting agencies, Mr Boulous said.

Finance Minister Scott Bacon said the state government believed any reforms on the advertising of betting should be determined nationally.

``Gambling advertising or sponsorship arrangements, conducted at sporting grounds or elsewhere in Tasmania by gambling operators licensed in Tasmania, must comply with the Tasmanian Gaming Commission's Responsible Gambling Mandatory Code of Practice,'' he said.

``This includes a responsible gambling message that includes the name and phone number for the gambling helpline to be included in all media advertising.

``Gambling operators that are not licensed in Tasmania, while not captured by the Commission's Code of Practice, are actively encouraged to comply with the code requirements when advertising in Tasmania.''

Human Services Minister Cassy O'Connor said the government had invested in the Gamblers Help services, including face-to-face counselling, financial counselling, community-based education and a 24-7 gamblers helpline.

The Know Your Odds anti-gambling campaign also operates in Tasmanian schools and the community, and this year the campaign had been extended to include sponsorship of the Hobart Chargers and the Devon Netball Association in an effort to raise awareness of problem gambling at sporting events, Ms O'Connor said.
