Nov 19 (Reuters) - Australia shares inched higher on Friday, with financials and the healthcare sector lifting the benchmark, while resource-related stocks weakened as commodities slid on broadening fears of rate hikes and inflationary risks.

The S&P/ASX 200 index was up 0.1% at 7,379.2 points, as of 1146 GMT. The benchmark, however, was headed towards a 0.8% weekly loss, its biggest since Oct. 29.
