Australia's Robyn Denholm will become the new chair of Tesla's board, replacing Elon Musk.
The electric car company said Ms Denholm will leave Telstra after a six-month notice period with Australia's biggest telco. The appointment takes effect immediately.
Ms Denholm already is on Tesla's board. The firm said her post as board chairwoman will be a full-time position.
It comes after Musk agreed to vacate his post as board chairman as part of a settlement with US regulators of a lawsuit alleging he duped investors with misleading statements about a proposed buyout of the company.
The settlement in late September with the Securities and Exchange Commission allowed Musk to remain chief executive of Tesla but required him to relinquish his role as chairman for at least three years.
Apart from appointing a new chairman, Tesla was required to appoint two new independent members to its board, to provide stronger oversight to match Tesla's growing stature and market value.

She has also worked at various technology companies including Juniper Networks and Sun Microsystems and held finance management posts at Toyota in Australia.
