April 3 (Reuters) - Australian shares rose on Monday to their highest in more than three weeks, helped by gains in technology and energy stocks, while investors awaited an interest rate decision from the Reserve Bank of Australia on Tuesday.

The S&P/ASX 200 index climbed 0.8% to 7,235.0 by 0044 GMT, hitting its highest since March 10. The benchmark rose 0.8% on Friday.

Hopes have grown that the Reserve Bank of Australia (RBA) could leave its benchmark interest rates unchanged on April 4 as recent economic data suggests 350 basis points (bps) of rate hikes since May last year have started to impact growth.

However, 14 of 27 economists polled by Reuters predicted that the RBA could go for a final 25-bp hike, while the remaining 13 saw a pause at 3.60%.

Among single stocks, Coles Group gained 0.6% after the country's No. 2 grocer acquired two automated milk processing facilities for A$105 million.
