In a statement, the company said the device weighed less than one kilogram, coming in at 989 grammes.
The Portégé X30W-J is powered by the new 11th generation Intel Core processor with the Intel Iris Xe Graphics engine.
Dynabook said the device was built as part of Intel's Project Athena innovation program and had achieved what is called the Intel Evo platform badge.
"The launch of the Intel Evo platform is a significant milestone for the industry and embodies our own commitment to the evolution of device innovation to meet the requirements of the modern mobile professional," said Angela Walker, director – Sales and Marketing, Dynabook ANZ.
"With many people now using their personal devices for both work and leisure, the Portégé X30W-J offers lightweight durability without scrimping on performance.
"It's a convertible laptop that easily fits into our modern lifestyle and is a great example of our shared philosophies with Intel for providing users with everything professionals need for uninterrupted productivity, creativity and collaboration."
The Portégé X30W-J screen is made of Corning Gorilla Glass and has a high-brightness, anti-glare Sharp IGZO display.
There are USB-C ports for both Wi-Fi 6 and Thunderbolt 4. The device will be sold in both Australia and New Zealand at prices beginning from A$2099 and NZ$2195 respectively.
Dynabook was acquired by Sharp in June 2018, having been owned by, and branded as, Toshiba from 1958 to 2018. The brand was used by Toshiba in other parts of Asia Pacific and it is now the brand name for Australia and New Zealand.
