If Israel and Indonesia do indeed normalize relations, this is tremendous news for Israel.
It is one of the 20 largest economies in the world, with a strategic location and significant needs (imports of over $235 billion a year) that Israel can partially meet, even if minimally.
First, the Israeli digital industry, SaaS companies, fintech, payments, and cybersecurity encounter a huge and growing market seeking cloud security, fraud detection, credit risk management, cross-border payments, and smart "know your customer" processes. Indonesia is a large market looking for solutions for banking operators, digital wallets, and online commerce.
Second, water, climate, and agritech. Indonesia struggles with pollution, floods, and seasonal droughts; water efficiency, smart agriculture, remote monitoring, and weather/disease forecasting are areas with clear technological demand that Israel can address.
