The announcement follows the appointment of Gladys Berejiklian MP as NSW Premier last week.
Mr Marshall said he was delighted to have responsibility for the portfolio and is looking forward to continuing making NSW the nation’s events capital.
“I am really looking forward to working closely with Destination NSW to ensure NSW maintains its position as the most visited state in Australia,” Mr Marshall said.
“This means positioning not only Sydney as a world-class tourism and events destination, but helping open up rural and regional NSW to more international and domestic tourists and building on the capacity for our regions to attract and host more major events.
“Having grown up on a farming property near Gunnedah in the state’s North West, I am proud to have lived and worked in regional NSW for many years.
“The newly created Destination Networks will deliver a framework to support continued growth and attract more visitors to rural and regional NSW.
“I am deeply honoured and privileged, and I’m really excited to sink my teeth into my new role.”
Mr Marshall previously served as the Parliamentary Secretary for Northern NSW and Renewable Energy.
