Australia shares track Wall Street rally to open higher

* Export-reliant healthcare rises as Australian dollar weakens

* Rio Tinto forms indigenous advisory group, shares rise

* AGL Energy extends gains for third straight session

March 23 (Reuters) - Australian shares opened higher on Tuesday, with healthcare leading the gains, as the benchmark index tracked an overnight rally on Wall Street after U.S. technology stocks rebounded from a recent selloff sparked by surging bond yields.

The S&P/ASX 200 index was up 0.22% at 6,752.5 points by 2330 GMT. The index closed 0.7% higher on Monday.

The three major U.S. indexes rose between 0.3% and 1.2%, with the tech-heavy Nasdaq outpacing its peers. A climb in Treasury yields have being weighing on high-flying technology stocks since mid-February.

Shares of export-reliant healthcare stocks rose 1% as the Australian dollar weakened. A weaker local currency tends to help healthcare companies earning in U.S. dollars.

Medical devices maker Resmed Inc gained 1.7%, and drugmaker CSL Ltd was up 0.6%.

Technology stocks mirrored their Wall Street peers to rise 0.7%, with buy-now-pay-later company Afterpay and artificial intelligence firm Appen Ltd advancing 1.2% and 0.9%, respectively.

The mining sub-index was also trading higher, with heavyweights BHP Group and Rio Tinto Ltd gaining 1.4% and 0.6%, respectively.

Rio Tinto said on Tuesday it would form an indigenous advisory group to improve protocols to manage indigenous culture, months after destruction of a sacred heritage site for a mine.

Utility stocks advanced 1.4%, with power supplier AGL Energy extending gains for a third consecutive session.

The number of issues on the ASX that advanced were 703 while 441 declined.

New Zealand’s benchmark S&P/NZX 50 index rose 0.5%, largely helped by gains among utility and industrial stocks.
