Exhibit 99.1

Trio-Tech Fiscal 2005 First Quarter Net Income Increased
to $0.08 Per Share Versus A Loss of $0.09 Per Share
As Revenue Increased 104%

Total Backlog Increased to $12.6 Million From $5.6 Million

     Van Nuys, CA, — November 12, 2004 — Trio-Tech International (AMEX:TRT) today announced substantially improved net income for the first quarter of fiscal 2005 compared to the prior year on a 104% increase in revenue. The company also announced that overall backlog at the end of the fiscal 2005 first quarter more than doubled compared to backlog at the end of the first quarter of fiscal 2004.

     Net income for the three months ended September 30, 2004 increased to $237,000 from a net loss of $265,000 for the first quarter of fiscal 2004. For the first quarter of 2005, earnings per diluted share was $0.08, compared to a net loss of $0.09 for the same period last year. Revenue for this year’s first quarter increased 104% to $7,851,000 from $3,850,000 for the same period of the prior year, the result of higher sales in each of the company’s operating segments.

     Total backlog at September 30, 2004 increased to $12,567,000 from $5,602,000 at September 30, 2003. Testing Services backlog increased to $7,980,000 from $4,051,000, Manufacturing backlog increased to $2,945,000 from $1,145,000, and Distribution backlog increased to $1,643,000 from $405,000.

     Shareholders’ equity rose to $9,299,000 at the end of the fiscal 2005 first quarter from $9,024,000 at the end of fiscal 2004. Cash and short-term deposits decreased to $5,871,000 at September 30, 2004 from $7,006,000 at June 30, 2004, primarily because of scheduled payments for the company’s previously announced acquisition of the semiconductor burn-in division in Malaysia.

Operations Review

     Manufacturing segment revenue increased to $3,978,000 for this fiscal year’s first quarter from $906,000 for the first quarter of fiscal 2004, as the company converted the unusually high backlog at the end of last fiscal year into sales during the period. Sales of the company’s burn-in systems and burn-in boards were especially strong during this year’s first quarter. However, since Singapore Manufacturing backlog at September 30, 2004 was lower than that of June 30, 2004, sales for this operation are expected to slow down in the second quarter of fiscal 2005.

     Distribution segment revenue increased to $979,000 for the first quarter of fiscal 2005 from $660,000 in the same period last year. This was attributable to increased demand for vibration equipment, chambers and wafer fabrication equipment.

     Testing Services revenue rose to $2,894,000 for this year’s first quarter from $2,284,000 for the first quarter of fiscal 2004. The recently acquired burn-in division in Malaysia contributed revenue of approximately $500,000 for this year’s first quarter, with the remainder of the increase representing higher burn-in volumes of a customer’s new semiconductor device that more than offset lower volumes of older semiconductor products.

     “Trio-Tech benefitted during the first quarter from stronger demand for our products and services, especially in the Asian market. Also important is that we continued to manage our costs carefully, especially our materials costs, and maintained low overhead expenses,” said President and Chief Executive Officer S.W. Yong.

     Yong added, “The increase in backlog is a positive sign, but our industry remains highly competitive with short lead times and continuing intense pricing pressure. In an effort to protect the company from these uncertainties, we have intensified our marketing efforts in each of our business segments, and expanded and upgraded our burn-in technology to enhance our competitive position and protect our market share. At the same time, we are exploring how we can use our technologies, manufacturing and service expertise, and customer relationships to enter new markets with attractive growth potential.”
