Venice is one of the world's top tourist destinations, with a trip on many people's bucket lists. But it's also battling over tourism, with around 20 million tourists a year flocking to the unique lagoon destination. In the latest crackdown, it has banned large tour groups.

That's on top of charging a fee for people to visit on certain weekends.

"The reason behind it is to try and deter people from travelling on the busiest days," Kumi tells 9Travel.

"On the day that I bought the pass, it didn't seem to deter people from going on a Saturday. I honestly think it's too cheap. "If you've spent thousand of dollars to get to Venice, does five or ten Euros make a difference?" However, Kumi says she spoke to politicians in the city, who say the tourist tax trial has been a success and next year it's likely to be implemented on more days.

The cost could also double to $16 (€10). Kumi, who features in the SBS Dateline episode The Death of Venice on August 13, says she feels the city is at a "tipping point," with residents feeling like it's not a place for them anymore. "Rooms available for tourists, it outnumbers the number of people living there," she tells 9Travel.

Capping the number of Airbnb's available would also be a good idea in her view. READ MORE: The hotspot dup.
