There is no universally applied threshold for materiality of an amount. Nor does IFRS specify any method of determining materiality. Therefore it is up to the management to decide the materiality thresholds. However it is important to know how your auditor decides the materiality of an amount. Otherwise auditors may qualify your financial statements. Most companies consider any amount as material in internal audit.
By the way I worked for one of the big four audit firms and their materiality thresholds for planning purposes were 5% of the profit before tax from continuing operations and 0.5% of the revenue or total assets. Any amount above those thresholds were considered material.
