Design a high-resolution brochure image emphasizing Australian heritage for a line of beverage alcoholic essences. The top of the image should have a majestic, softly lit Australian landscape, including the iconic Sydney Opera House on the left and the red cliffs of the Australian outback on the right, all under a gradient sky transitioning from dawn to mid-morning blue. The central feature should be a clear, tranquil river winding through a lush, green Australian forest. Below the landscape, display a range of alcoholic essence bottles with sophisticated, rustic labels, each bottle showcasing different flavors like strawberry, lemon, and peach, and each adorned with intricate illustrations corresponding to their flavors. Each bottle should have a distinct, premium look with a 'Made in Australia' emblem prominently featured. At the bottom, the text 'MADE IN AUSTRALIA' should anchor the image, suggesting authenticity and quality. The image should convey a sense of premium, natural purity and target an audience of international investors and connoisseurs.
