The launch will be at 2pm AEDT, with the function to be an affair featuring augmented reality. OnePlus has encouraged those who want to watch the launch to download the OnePlus Nord AR app.
Additionally, OnePlus said it would be offering 900 of the new devices for pre-order on 8 July, but only in the EU and for a fee of €20 (A$32.40).
Customers in India will have to pay 499 rupees (A$9.55) through Amazon India to place pre-orders. Another incentive to buy is the offer of a OnePlus Bullets Wireless V1 headphones and a phone cover for those who buy the device by 31 August.
And it will be built on the Snapdragon 765G Soc with a flagship camera. The device will not be launched in North America first, with the company's chief executive, Pete Lau, saying: "We are going to start relatively small with this new product line by first introducing it in Europe and India.
"But don't worry, we're also looking to bring more affordable smartphones to North America in the near future as well."
The OnePlus 8 has made a decent impact in the US to the extent that both T-Mobile and Verizon are offering it on plans.
Majority owned by OPPO, a subsidiary of BBK Electronics, OnePlus is sold in 34 countries and is headquartered in Shenzhen.
