However, the boofy-haired Queen guitarist could not have penned a more accurate summary of the conundrum facing our state's tourism chiefs.

Having long been the island state's greatest visitor drawcards, many of Tasmania's national parks find themselves in need of minimising visitation in order to maximise appeal.

Last month, 250 people attended a meeting at the Coles Bay Community Hall to discuss concerns over the revised draft Freycinet Peninsula Master Plan.

Topping the agenda was the suggestion of imposing a cap on visitors entering Freycinet, undoubtedly the Bohemian Rhapsody of Tasmanian national parks.

Second in popularity, much like Another One Bites the Dust, is Cradle Mountain National Park which has already introduced methods to limit vehicle access to Dove Lake and walker numbers on the Overland Track.

The fear is that while natural beauty is what keeps tourists coming to Tasmania, if too many come that beauty might not be so beautiful.

This is particularly the case where facility investment has not kept pace with visitation.

Two more national parks provide perfect examples of this.

The Walls of Jerusalem have long been the hidden gem among Tasmania's crown jewels - much like the oft-overlooked classic Hammer to Fall (also written by May for the 1984 album The Works).

However, while visitor numbers have neared 8000 per year, the only toilets to be found in 500 square kilometres are a couple of modest long drop efforts at Wild Dog Creek and Dixons Kingdom. As both are several hours walk away, toilet tissues and obnoxious odours are as abundant around the car park as marsupials and myrtles.

All of which prompted the recent $312,000 development application for a new car park, walker registration and toilet block which suggested the "ever increasing" toilet waste might just be detracting from the visitor experience.

Maria Island (minimalist, simplistic but brilliant, like We Will Rock You) has faced similar issues.

The 23,000 visitors that travelled to the idyllic East Coast getaway in 2015-16 represented an increase of 10 per cent on the previous year. So, in April 2017, amid the usual fanfare that accompanies any government announcement, Environment and Parks Minister Matthew Groom launched a new ferry intended to provide five sailings a day each way during peak periods.

"It's another significant marker in our plan to attract 1.5 million visitors to the state by 2020," he said. "I look forward to further tourism growth for the island with the new ferry service now up and running."

Sure enough, the following year visitor numbers jumped by a third to 31,000.

However, while money was being invested in getting more people to the island, none was going in to facilities awaiting them which is understood to have prompted the same pungent inadequate sanitation scenario as the Walls of Jerusalem.

Parks and Wildlife figures also reveal that Freycinet topped the visitation table in 2017-18 with 310,000 (up 6 per cent) while Cradle Mountain had 280,000 (+11 per cent) and was followed by Tasman (203,000, +6 per cent) and Mount Field (196,000, +1 per cent) national parks - those big four being double any other Tasmanian location.

With elections going on and specific government expenditure particularly topical, it's worth remembering that Tasmania's Parks and Wildlife Service manages 19 national parks and more than 800 reserves.

Tourism Tasmania's latest visitor survey results show that in 2018, 1.32 million people visited the state (up 4 per cent), spending a combined 10.83 million nights here and, more importantly, 2.46 billion dollars (up 5 per cent).

Too much love might not necessarily kill Tasmania, but something's got to give when resources are Under Pressure.
