Federal Treasurer Wayne Swan cautioned the tourism industry on Tuesday that the sector is in danger of suffering anew from the effects of a two-speed economy if the Labour's proposed tax measures are not implemented.

Mr Swan told a tourism and transport forum in Canberra that the resurgence of boom conditions in the mining sector could spell disaster for industries such as tourism, manufacturing and construction.

He underscored the fact that these three sectors could find it much harder "to attract workers and capital, and the stronger dollar makes you less competitive in your own global markets."

Mr Swan noted that in a two-speed economy, the government is obliged to do its best to push for growth on sectors, such as tourism, but without imposing any regulation on a booming industry such as the mining sector.

He said that this is the reason why a third of revenues to be collected from the proposed super profits tax would be utilised to slash corporate tax from 30 percent to 28 percent come 2014/15.

Mr Swan noted that at present, the Australian economy still operates in under-capacity mode but it is gearing for the time when it reaches full-capacity again and since "we performed beyond expectations, we'll deal with re-emerging capacity constraints sooner than other nations with weaker economies."

And the mining sector could be the most hit hard should economic contraction again occurred and with that in mind, the federal government is poised to invest $6 billion in fresh regional infrastructure fund for building rail, roads and other key infrastructure in support of the mining regions and communities.

In this light, Mr Swan reminded the transport sector that they must be aware that the government has allowed the national infrastructure deficit to balloon for some years in order to face such eventuality.
