SYDNEY, Feb. 7 (Xinhua) -- After 10 tourists died during a six month period at the end 2016, the Queensland (QLD) State Government in Australia set about tightening regulations for dive operators on the iconic Great Barrier Reef.

After more than one year of consultations, the snorkeling and scuba code of practice has now come into force on Wednesday, with an array of new safety measures to improve one of the state's favourite recreational activities.

"Queensland has the largest recreational snorkelling and diving sector in Australia and we're the only state to have specific legislation covering the industry," QLD industrial relations minister Grace Grace said.

"We have had extensive consultation with industry and I am confident that this finalized code will ensure visitors who are diving and snorkeling in our state feel it is being done in the safest manner possible."

Under the new rules, vessels are required to carry automatic external defibrillators and ensure instructors are well positioned to render assistance in the case of an emergency.

Operators have also been made to enhance supervision and implement better systems to identify "at-risk snorkelers" prior to them entering the water.

With 175 snorkelling deaths in Australia over the last 13 years, QLD member of parliament Craig Crawford said it's imperative visitors that contribute to the local economy be kept safe on the reef.

"This code is crucial for Far North Queensland tourism and the local economy," he said.

"Our industry strives to ensure world's best practice and now that this code has been signed off, we have achieved this."

"It will ensure Queensland continues to lead the way on reef and water safety and make the reef an even safer place to visit for tourists."
