If you only intend staying for 3 weeks and your accommodation will be provided by your friend, evidence that you have savings of €5000 will show that you have sufficient funds to pay for your expenses. You're an Israeli (which while designated as a high risk country, has a very low rate of overstaying Australian Tourist visas - in fact lower than the UK and USA), you have a good job with a letter from your employer to that effect, you have ample funds - I very much doubt if you will have any problem getting a visa or that it will take as long as 4 weeks.
