There were earlier media reports that the cash starved SLCB was not in favour of using the system which is roughly estimated to cost US $5,000 per day.
Upali Dharmadasa, the SLC interim committee chairman, told a leading cricket website on Saturday: "The use of DRS is a priority for us, since the decision was taken during the ICC annual conference in Hong Kong, to use it in all series, which all the members agreed to."
The ICC has stipulated that DRS will be made compulsory with effect from 1st October. The boards can decide weather they want to make use of the ball-tracking system or not.
Dharmadasa said SLC still had a few questions about the DRS that would be resolved by next week. "Regarding the predictive path, we have written to the ICC and the final decision will be taken at the SLC meeting on Wednesday."
The Sri Lankan board has run into financial difficulties after cost overruns in the building of new stadiums at Hambantota and Pallekele while the existing R Premadasa stadium was completely renovated ahead of the World Cup which it co-hosted with India and Bangladesh.
The Sri Lankan board has already slashed the budgetary considerations for this series from 300 million rupees to 100 million rupees after the sports minister Mahindananda Aluthgamage said austerity measures had to be taken. Dharmadasa, however, said "funding for DRS is not an issue."
Australia are set to arrive at the island nation towards the end of this month for a tour that includes 2 T20's, 5 ODIs and 3 Test matches.
