Demand for international assets fell by 2 per cent in August 2014, but high net worth investors are continuing to show interest, Certitude said.
But this does not seem to be the case among high net worth investors and those who receive advice, where demand for global investments is sitting at a level roughly equal to the six month high, the Certitude Global Investing Intentions Index (CGIII) showed.
"We know that HNW investors are significantly more likely to be taking expert advice, for example they are likely to be considering international managed funds covering multiple regions in their portfolio," Certitude CEO Craig Mowll said.
The index also showed those who want international exposure via actively managed funds increased by 6 percentage points to 39 per cent, beating direct purchase of overseas shares (37 per cent), which fell by 4 percentage points.
Forty three per cent of investors planning to invest overseas intend to do so within the next three months, a rise of 5 percentage points and a seven month high.
More than half of high net worth investors (55 per cent) are planning to invest offshore over the next three months.
There has also been a steep decline in confidence in Australian equities.
"Although we are seeing an overall slowdown in demand for Australian and international shares, we continue to see desire for an asset allocation less heavily skewed to Australian equities with advised and high net worth investors leading the charge," Mowll said.
He added this trend will continue, especially if advisers help clients through uncertain times.
